The faithful trust in the help of the Mother of God – who in France is always venerated under the title “Notre-Dame” (which corresponds to the German name “Our Lady”) – was expressed by the French nun, mystic and Doctor of the Church, Saint Thérèse of Lisieux (religious name Thérèse of the Child Jesus and the Holy Face, 1873 to 1897) as follows: “In trials or difficulties I turn to Mother Mary, whose gaze alone is enough to dispel all fear.”
